FABRIC-FOLDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 511,977, dated January2, 1894.

Application filed July 26, 1893.

To all whom it may concern.-

Be it known that I, MARY TOBENER, a citizen of the United States, and aresident of Gold Hill, in the county of Storey and State of Nevada, haveinvented certain new-and useful Improvements in Sewing-MachineAttachments; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to sewing machine attachments of that class knownas folder or seam finishers, and has for its object to fold or finish aseam by asimple construction and arrangement of. parts, which arereadily attachable or detachable to and from a sewing machine.

With this and other objects in view, the invention consists of theconstruction and arrangement of the several parts, which will be morefully herginafter described and claimed.

In the drawings: Figure 1 is a perspective view showing the improvedattachment applied in operative position. Fig. 2 is a perspective viewof the attachment disconnected, and shown on a larger scale. Fig. 3 is asection on the line 0ca; Fig. 2. Fig. t is a transverse section on theline y-y, Fig. 6. Fig. 5 is a detail perspective view of a piece offabric which has been folded by the attachment. Fig. 6 is a sideelevation of the device.

Similar numerals of reference are employed to indicate correspondingparts in the several figures.

Referring to the drawings, the numeral l designates an arm, having aloop or sleeve 2 at one end' thereof, in which is fitted a removablefastening screw 3, having a portion of its shank smooth and notthreaded. This construction is for the purpose of securing theattachment to a sewing machine but it is to be understoodthat no stressis to be laid upon this arrangement, as any preferred means may beemployed for applying the attachment. The arm 1 is positioned in theproper plane and at the proper angle to ac- Serial No. 481,524. (Nomodel.)

commodate the attachment and operation of the device, and at its freeend is secured a conical shaped folding sleeve 4:, with a slot 5extending the full length of one side thereof. Within the said conicalsleeve is a divider 6, formed by inturning the edges of the said sleeveon the side opposite that to which the slot is formed, and the saiddivider stands away from the side of the sleeve in which the said slotis located. The divider extends through the larger end of the sleeve andthroughout its length it partakes of the same degree of widthproportionately to the increase of the width of the said sleeve from itssmaller toward its larger end. The end of the divider which projectsthrough the sleeve is separated and the two parts are bent laterally inopposite directions at slight oblique angles to provide folders orformers 7.

The fabric to be folded has the two edges thereof placed in the slot 5and is turned and fed to the needle and simultaneously connected toproduce the form shown in Fig. 5. It will be seen that this finishes aseam and makes a strong connection without the use of binding. When thetwo pieces of fabric are inserted in the slot, the edge of each iscaused to assume a position on opposite sides of the divider, and asthey are drawn under, are turned inward or under, and in this conditionare ready to be seamed by the machine.

The attachment entire is simple and effective in its construction andoperation, is easily manufactured, and can be readily applied ordetached. It is adapted to be used in connection with any form or makeof ma chine, and the essential feature of the invention resides in theconical sleeve and the divider therein of the nature set forth.

Having thus described the invention, what is claimed as new is- In asewing machine attachment for the purpose set forth, a conical sleevesuitably supported having a dividing partition secured to one of theinner sides of the sleeve and extending toward the opposite inner sidethereof, said divider extending through and projecting outwardly fromthe larger end of said sleeve and tapering proportionately to Intestimony whereof I have signed this the taper of the sleeve, with theparts of said specification in the'presence of two subscribfreeprojecting end extended laterally in oping witnesses.
